Spoke with Charlie. He said it is mostly a regional thing with the cape guys wanting rollers and RI guys preferring conventional.He cited the failure rate with rollers with lines getting cut due to inexperience in most cases. He says he replaces a fair amount of roller tips that fail every year mostly from wire getting caught outside the roller. In conclusion,he didn't seem to think a roller is a must on wire rods.FWIW the majority of guys in that shop have been there for a long time and are short on BS.
